WATER-JET DEVICE.

Application filed May 13, 1924. Serial No. 713,036.

To all whom it may concern:

Be it known that 1, JOHN ARMSTRONG, a citizen of the United States, residing at Cattaraugus, in the county of Cat-taraugus and State of New York, have invented or discovered certain new and useful Improvements in VVater-Jet Devices, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to a water jet device more particularly intended for use in a can washing machine for throwing a jet of rinsing water into an inverted milk can, after the same has been emptied, to remove any remaining milk before the can is subjected to the action of a cleansing liquid which is used to clean the can thoroughly. The invention comprises a casing affording a hollow body having a cold water inlet and into the chamber of which extends a pipe for the inlet of steam under pressure, said pipe communicating with a steam jet nozzle supported in said chamber and preferably on a tubular member having openings adjacent said nozzle, and having a water jet nozzle extending outward from said 1101- low body. The outlet end of said steam jet nozzle is adjacent to but spaced apart from said water jet nozzle a sufficient distance to permit water to flow in between said steam jet nozzle and the inner end of said water jetnozzle, so that the steam issuing from said steam jet nozzle will force the water through said water jet nozzle, with considerable force, into the can to be cleansed.

The accompanying drawing is a vertical section of the improved water jet device.

Referring to the drawing, 12 denotes a casing provided with an internally threaded boss 13 for the attachment thereto of a water inlet pipe. Screwed into one end of said casing is a cup-shaped nut 14 in which is fixed a steam inlet pipe 15 having an inner threaded portion 15 and an outer threaded portion 15, said last-named threaded portion receiving a union or coupling 16 having a threaded nipple for the attachment thereto of a steam inlet pipe. The outer threaded portion of said "union is adapted to be secured to a threaded support for the said water jet device.

Screwed onto the inner threaded portion 15 of the pipe 15 is a tubular member comprising a hollow part 17 a skeleton or open-work part 17 and a water jet nozzle part 17*. Fixed to the said hollow part 17 isa steam jet nozzle 18 the outlet end of which is adjacent to but separated from the inner endof the nozzle 17, thus leaving a space between these parts intowhich the water entering the chamber of the casing or hollow-body 12 may flow, so that steam issuing from thesaid nozzle 18 will force a jet of water through the nozzle part 17 with considerable force.

The exit end of the casing or hollow body 12 is closed in any-suitable manner, as by a disk 19 through which the nozzle 17 extends, and this disk may be secured in place 111 any desired way. 7

The structure just described provides a simple and convenient water jet device whereby water may be forced by steam or other fluid pressure through the nozzle 17 in a strong jet, for the purpose stated, or for any other purpose where a device of this kind is adapted for use. 7

Having thus described my invention 1 claim and desire to secure by Letters Patent:

1. A water jet device comprising a hollow body having awater inlet, a steam inlet pipe communicating with the chamber of said hollow body, a tubular member mounted in said hollow body and having a partly open portion within said chamber, a water jet nozzle extending outside of said chamber, and a steam jet nozzle within said partly open portion, the outlet end of said steam nozzle being adjacent to but separated from the inner end of said water jet nozzle.

2. A water jet device comprising a hollow body having a water inlet at one side, a nut screwed into one end of said hollow body, a steam inlet pipe fixed to said nut, a tubular member having an openworkpart within the chamber of said hollow body, a water jet nozzle extending outside of said chamber, and a steam jet nozzle within said openwork part of said tubular member, the outlet end of said steam jet nozzle being adjacent to but separated from the inner end of said water jetnozzle.

In testimony whereof I aflix my signature.

JOHN ARMSTRONG.
